Technical Field

Background

The data transmission rate is the average number of bits, characters transmitted between respective devices in the data transmission system per unit time. The corresponding devices refer to a PCIe (peripheral component interconnect express, hereinafter referred to as PCIe) controller and a solid state disk supporting a PCIe interface channel. PCIe supported data transfer rates are 2.5GT/s, 5.0GT/s, 8.0GT/s, 16.0GT/s, etc. For example, an X4 solid state disk supporting 16.0GT/s must be able to normally operate on a 16GT/s platform with a theoretical performance close to 4GB/s, and must also be able to normally operate on a computer supporting only 2.5GT/s or 8 GT/s.
